Ingredients You’ll Need

Before you start, gather these ingredients:

For the Cupcakes:

  • 2 ½ cups all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 cup milk (whole or 2%)
  • 1 teaspoon vanilla extract
  • Gel food coloring (pink, blue, yellow, purple, green)

For the Frosting:

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 2-3 tablespoons milk
  • 1 teaspoon vanilla extract
  • Gel food coloring (optional for swirls)
  • Edible glitter or sprinkles for decoration

Step 1: Prepare the Batter

Preheat your oven to 350°F (175°C) and line a cupcake tin with 12 liners.

In a medium bowl, mix the flour, baking powder, and salt. Set aside.

In a large bowl, beat the butter and sugar with an electric mixer until light and fluffy (about 3 minutes).

Add the eggs one at a time, mixing well after each addition.

Mix in the vanilla extract.

Gradually add the dry ingredients and milk, alternating between the two, starting and ending with the dry ingredients.

Mix until just combined.

Step 2: Color the Batter

  1. Divide the batter evenly into five small bowls.

2. Add a few drops of gel food coloring to each bowl (one color per bowl).

Stir until the colors are vibrant and even.

Layer the colored batter into the cupcake liners.

Add a spoonful of one color, then layer another color on top, and so on until each liner is about ¾ full.

Step 3: Bake the Cupcakes

  1. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
  2. Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely before frosting.

Step 4: Make the Frosting

In a large bowl, beat the butter until creamy.

Gradually add the powdered sugar, 1 cup at a time, mixing on low speed.

Add the vanilla extract and 2 tablespoons of milk.

Mix until the frosting is smooth and spreadable. If it’s too thick, add another tablespoon of milk.

To create a rainbow swirl effect, divide the frosting into separate bowls, color each with gel food coloring, and spoon the different colors side-by-side into a piping bag.

Step 5: Decorate the Cupcakes

  1. Pipe the frosting onto the cooled cupcakes in a swirl pattern.
  2. Sprinkle the tops with edible glitter or rainbow sprinkles for extra sparkle.
  3. Optional: Add small unicorn toppers or candies for a whimsical touch.

Tips for Success

  • Use gel food coloring: It gives vibrant colors without thinning the batter.
  • Don’t overfill the liners: Leave room for the cupcakes to rise.
  • Practice frosting swirls: Try a few swirls on parchment paper before decorating the cupcakes.
